GOVERNOR FOR ADDlNG, COUNTING, AND REGISTERING MACHINES SPECIFICATION forming part of Letters Patent No. 367,346, dated July 26, 1887.

Application filed October 16, 1586. Serial No. 216,430. (No model T0 aZZ whom, it may concern.-

Be it known that 1, WILLIAM KOCH, of the city, county, and State of New York, have invented a new and useful Governor for Adding, Counting, and Registering Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which Figure l is a sectional view of my improved governor for adding, counting, and registering machines,illustrating the same as geared to the crank-shaft ofa check printing and adding machine, Fig. 2 being an end view of the same chine, partly in section, in line 0000. Fig. 3 is a view in perspective of the governor-wheel detached, and Fig. 4 an under side view of the same; Fig. 5, a'view in perspective, illustrating a modification of the governorwhecl,

wherein the upper plate or disk is dispensed with. Fig. 6 is a view of a portion of a cashregister with the improved governing device connected thereto, the front plate of the machine being removed and the governor shown in section; and Fig. 7 is a section in line y y of Fig. 6, with a portion of the end of the case of the machine broken. away.

In the'use of devices made to indicate the number ofsingle revolutions ofashaft by means of a train of geared wheels bearing numerals such as are commonly employed in connection with machines for counting, adding, or registering, aud-whieh are customarily operated by short, sharp movements, as by the single turn ofa crank, the depression of akey, or the move ment of a lever-there is a constant tendency and liability to error, in view of the difficulty in arresting the momentum ofthe movingparts, and especially ofthe counting or adding wheels,

, a momentum created by the quick, sudden movement thereof, and which causes the count ing-wheels to overthrow or pass beyond the proper limit of movement required therein.

The object of my invention is to overcome this tendency by preventing a quick, sudden movement of the operative parts and so to control them as that, however great or sudden may be the application of drivingpressure thereto, they shall move with an easy, steady motion and stop with ease and precision. This object is attained in my invention by combining with a paddle-wheel geared to the main shaft or spindle by which the counting-wheels are driven and with a closed vessel in which said paddle-wheel revolves a charge of viscous or gelatinous fluid, so that the friction of the thick fluid within its inclosing-ehamber as it is carried around therein by the movement of the wheel will operate to prevent effectually any sudden jerk of the train of gearing, and so govern the driving impulse as to convert it into a steady, uniform,.equable motion.

In the accompanying drawings, A represents the main or driving shaft or spindle by whose rotation a train, B, of adding, counting, or registering wheels is driven, said wheels being arranged and geared in any well-known man- 'ner, whereby each wheel in the series is made to indicate a definite number of the revolutions made by that preceding it.

C is a suit-able vessel or casing, within which is stepped a central spindle, D, extending out therefrom and properly supported in suitable bearings, E E, so as to be free to revolve upon its axis. The outer end of this spindle is geared, by suitable spur or bevel wheels, F F, mediately or immediately to the driving-shaft A, and upon its lower end are fitted a series of radial blades, G G, adapted to form movable partitions in the vessel 0, which shall revolve therein with the spindle D. The edges of the blades or partition-plates G G are made to approach very closely the inner surfaces of the bottom, sides, and top of the vessel, and the vesselis completely covered in and inclosed by a top plate, H, bolted or otherwise secured thereon. The radial plates carried by the spindle constitute a governor-wheel revolving in the case 0.

For the sake of greater convenience in filling the vessel, the top may be provided with an opening, to be closed by a plug, K.

L, Fig. 1, represents the crank by which the adding or counting wheels 13 and the spindle D of the governor-wheel are driven; or they may be driven by the movement of one or more key-levers, M M, engaging and actuating the main shaft A by means of pawls and ratchets P, as shown in Figs. 6 and 7.

The governor-wheel may be formed with a top plate or head, N, connecting its radial blades, (see Figs. 1, 3, 4, and 6;) or the blades may project free from the spindle, as shown in Fig. 5. In either case they are made to e:'- tend far enough to move closely to the sides of the casing, so as to prevent a free flow of the liquid by them and compel the mass thereof to rotate with them.

For use,the vessel Gis filled completely with a viscous or gelatinous solution, which may consist of oil admixed with sufficient potash and water to partially solidify it to about the consistency of soft soap. Pure oil or water would be comparatively useless, as lacking in quality to produce the desired friction when carried rapidly over the inner surfaces of the inelosing vessel or casing. Sufficient friction may be obtained only by means-of a comparatively thick fluid, substantially as is above de scribed.

In the operation of the governor thus constructed, and connected with a train of adding, counting, or registering wheels, when the op crating-crank L or key-lever M is turned or struck, so as to rotate the shaft A, and with it the spindle D and governor-wheel, the friction of the fluid in the vessel 0 offers such resistance to the movement of the wheel as to prcvent effectually a sudden start thereof, while it will offer no sensible resistance to astead y, even movement of the crank or key. The wheel will revolve easily under a steady pressure, but will resist positively any quick or sudden impulse or pressure, the resistance offered thereby increasing in proportion as the impulse may be quick and sharp. Hence a heavy strong blow will not move the wheel, while it will turn readily under a gentle pres.- ure.

I am aware that a fly-governor constructed of vanes revolving in the air has been combined with a counting mechanism to steady its movement, and that a governor constructed of 40 a fan revolving in water has been combined with the works of a water-meter to secure a uniform movement therein; but I have found by experiment that neither of these devices are effective to prevent such a movement of 4 the adding-wheels in a chcclemachine under the influence of the short, quick stroke usually imparted to its key or crank in practical use, as will cause the adding-wheels to overthrow and impair the value and efficiency thereof. My invention overcomes this di lliculty by pro viding and combining with a fan or paddle wheel revolving within a closed casca resisting medium which, without effecting the proper normal movement of the wheel, will, by rca- 5 son of its specific gravity and its frictional resistance, check or arrest an abnormally-rapid movement thereof.

I claim as my inveution- The combination, with one or more count ing, adding, or registering wheels, at spindle geared thereto, a closed case orvesscl within which the spindle rotates, and a set of radial blades carried by the spindle to revolve there with within the closed case, of a viscous llnid or compound, substantially as described, filling said case, so as to be moved by the blades, substantially in the manner and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence oftwo sub scribing witnesses.

WILLIAM KOCH. \Vitnesses:
